5 Pre-Installation Considerations

5.1 Preparation

Keep this document with the unit. Carefully read all instructions for the installation prior to installing product. Make
sure each step or procedure is understood and any special considerations are taken into account before starting
installation. Assemble all tools, hardware and supplies needed to complete the installation. Some items may need to
be purchased locally. Make sure everything needed to install the product is on hand before starting.

5.2 System Matches

The entire system (combination of indoor and outdoor sections) must be manufacturer approved and Air-Condition­ing, Heating, and Refrigeration Institute (AHRI) listed. NOTE: Installation of unmatched systems is not permitted and
will void the product warranty.

5.3 Interconnecting Tubing

Give special consideration to minimize the length of refrigerant tubing when installing air handlers. Refer to Remote
Cooling/Heat Pump Service Manual RS6200006, and TP-107 Long Line Set Application R-410A for tubing guidelines. If
possible, allow adequate length of tubing such that the coil may be removed (for inspection or cleaning services) from
the cabinet without disconnecting the tubing.

3

5.4 Clearances

The unit clearance from a combustible surface may be 0". However, service clearance must take precedence. A
minimum of 24" in front of the unit for service clearance is required. Additional clearance on one side or top will be
required for electrical wiring connections. Consult all appropriate regulatory codes prior to determining final clear­ances. When installing this unit in an area that may become wet (such as crawl spaces), elevate the unit with a
sturdy, non-porous material. In installations that may lead to physical damage (i.e. a garage) it is advised to install
a protective barrier to prevent such damage. Always install units such that a positive slope in condensate line (1/4"
per foot) is allowed.

5.5 Horizontal Applications

If installed above a finished living space, a secondary drain pan (as required by many building codes), must be
installed under the entire unit and its condensate drain line must be routed to a location such that the user will see
the condensate discharge.

6 Installation Location

NOTE: These air handlers are designed for indoor installation

only.
The ARUF**14** and ASPT**14** product lines may be installed in

one of the upflow, downflow, horizontal left or horizontal right
orientations as shown in Figures 2, 3, 4 and 5. The unit may be
installed in upflow or horizontal left orientation as shipped (re­fer to specific sections for more information).

Minor field modifications are necessary to convert to downflow
or horizontal right as indicated in below sections.

Side Drain Pan Removal: Refer to Figure 1, remove the two (2)
screws that secure the drip shield support brackets to the
condensate collectors (front and back). Unsnap the side drain
pan from vertical (bottom) drain pan using a screw driver or any
small lever. The side drain pan and drip shield brackets may now
be removed. The bottom left drain connection is the primary
drain for this application and condensate drain line must be
attached to this drain connection. The bottom right drain
connection is for the secondary drain line (if used).

6.1 Upflow Installation

No field modifications are mandatory however to obtain maxi­mum efficiency, the horizontal side drain pan & extension must
be removed.

DRIP SHIELD REMOVAL

Figure 1

6.2 Horizontal Left Installation

No field modifications are permissible for this application.
The bottom left drain connection is the primary drain for this application and condensate drain line must be attached to

this drain connection. The bottom right drain connection is
for the secondary drain line (if used).

6.3 Downflow

No field modifications are mandatory however to obtain
maximum efficiency, the horizontal side drainpan & exten­sion must be removed.

IMPORTANT NOTE: To prevent coil pan “sweating” in the
downflow application, a downflow kit (DFK) is available
through your local distributor. The DFK is not supplied with
the air handler and is required by the manufacturer on all
downflow installations. See Table 1 for the correct DFK and
follow the instructions provided for installation.

6.4 Horizontal Right Installation

Side drainpan extension must be removed for all models except : ARUF47D14**, ARUF61D14**, ASPT61D14**.

Refer to Figure 6 and 7 for the location of the components referenced in the following steps.

1. Before inverting the air handler, remove blower access panel and coil access panel. The coil access panel and tubing
panel may remain screwed together during this procedure. Remove and retain the seven (7) screws securing the coil
access panel to the cabinet and the six (6) screws securing the blower access panel to the cabinet.

2. Slide the coil assembly out from the cabinet. Use the drain pan to pull the assembly from the cabinet.

NOTE: DO NOT USE MANIFOLDS OR FLOWRATOR TO PULL THE COIL ASSEMBLY OUT. FAILURE TO DO SO MAY
RESULT IN BRAZE JOINT DAMAGE AND LEAKS.

3. Removal of the center support is required on units
with 21" wide cabinet. Remove and retain the two
(2) screws that secure the center support to the cabi­net. Remove the center support.

4. Using the drain pan to hold the coil assembly, slide
the coil assembly back into the cabinet on the
downflow brackets as shown in Figure 8.

5. Re-install the center support (if removed) using the
two (2) screws removed in Step 4.

6. Re-install the access panels removed in Step 1 as
shown in Figure 9.

7. The bottom right drain connection is the primary drain
for this application and condensate drain line must
be attached to this drain connection. The bottom left
drain connection is for the secondary drain line (if
used). Install the PVC plug that was removed from
the side drain pan primary connection and install it
on the vertical primary connection.

NOTE: If removing only the coil access panel from the
unit, the filter access panel must be removed first. Fail­ure to do so will result in panel damage.

7 Refrigerant Lines

NOTE: Refrigerant tubing must be routed to allow adequate

access for servicing and maintenance of the unit.
Do not install the air handler in a location that violates

the instructions provided with the condenser. If the unit
is located in an unconditioned area with high ambient

temperature and/or high humidity, the air handler may
be subject to nuisance sweating of the casing. On these
installations, a wrap of 2" fiberglass insulation with a vapor
barrier is recommended.

7.1 Tubing Size

For the correct tubing size, follow the specification
for the condenser/heat pump.

7.2 Tubing Preparation

All cut ends are to be round, burr free, and clean.
Failure to follow this practice increases the chances
for refrigerant leaks. The suction line is spun closed
and requires tubing cutters to remove the closed end.

NOTE: To prevent possible damage to the tubing joints, do not handle coil assembly with manifold or flowrator tubes.
Always use clean gloves when handling coil assemblies.

7.3 Special Instructions

This product is factory-shipped with R410A and dry
nitrogen mixture gas under pressu re. Use appr opria te
service tools and follow these instructions to prevent
injury .

A quenching cloth is strongly recommended to prevent
scorching or marring of the equipment finish when
brazing close to the painted surfaces. Use brazing
alloy of 5% minimum silver content.

CAUTION

Applying too much heat to any tube can melt the tube. Torch
heat required to braze tubes of various sizes must be
proportiona l to the s ize of th e tub e. S erv ice p ersonn el m u st
use the appropriate heat level for the size of the tube being
brazed.

Units without a factory installed TXV come equipped with a flowrator piston for refrigerant expansion. For most
installations with matching applications, no change to the flowrator piston is required. However, in mix-matched
applications, a flowrator piston change may be required. See the piston kit chart (provided in the literature packet)
or consult your local distributor for details regarding mix-matched flowrator piston sizing. If the mix-match appli­cation requires a different flowrator piston size, change the flowrator piston in the flowrator body on the indoor
coil before installing the coil and use the procedure in section 8.4.

NOTE: The use of a heat shield is strongly recommended when brazing to avoid burning the serial plate or the finish

of the unit. Heat trap or wet rags must be used to protect heat sensitive components such as service valves and TXV
valves sensing bulb.

1. Remove refrigerant tubing panel or coil (lower) access panel.

2. Remove access valve fitting cap and depress the valve stem in access fitting to release pressure. No pressure indi­cates possible leak.

3. Replace the refrigerant tubing panel.

4. Remove the spin closure on both the liquid and suction tubes using a tubing cutter.

5. Insert liquid line set into liquid tube expansion and slide grommet about 18" away from braze joint.

6. Insert suction line set into suction tube expansion and slide insulation and grommet about 18" away from braze joint.

7. Braze joints. Quench all brazed joints with water or a wet rag upon completion of brazing.

8 Condensate Drain Lines

The coil drain pan has a primary and a secondary drain with 3/4" NPT female connections. The connectors required are 3/
4" NPT male, either PVC or metal pipe, and should be hand tightened to a torque of no more than 37 in-lbs. to prevent
damage to the drain pan connection. An insertion depth of approximately 3/8” to 1/2” (3-5 turns) should be expected at
this torque.

1. Ensure drain pan hole is not obstructed.

2. To prevent potential sweating and dripping on to finished space, it may be necessary to insulate the condensate drain
line located inside the building. Use Armaflex® or similar material.

A secondary condensate drain connection has been provided for areas where the building codes require it. Pitch all drain
lines a minimum of 1/4" per foot to provide free drainage. Provide required support to the drain line to prevent bowing.
If the secondary drain line is required, run the line separately
from the primary drain and end it where condensate discharge
can be easily seen.

NOTE: Water coming from secondary line means the coil pri­mary drain is plugged and needs immediate attention.

If secondary drain is not installed, the secondary
access must be plugged.

Insulate drain lines located inside the building or above a fin­ished living space to prevent sweating. Install a condensate
trap to ensure proper drainage.

NOTE: When units are installed above ceilings, or in other locations
where damage from condensate overflow may occur, it is MANDATORY
to install a field fabricated auxiliary drain pan under the coil cabinet
enclosure.

The installation must include a “P” style trap that is located as close as
is practical to the evaporator coil. See Figure 12 for details of a typical
condensate line “P” trap.

NOTE: Trapped lines are required by many local codes. In the absence
of any prevailing local codes, please refer to the requirements listed in
the Uniform Mechanical Building Code.

A drain trap in a draw-through application prevents air from being drawn back through the drain line during fan opera­tion thus preventing condensate from draining, and if connected to a sewer line to prevent sewer gases from being drawn
into the airstream during blower operation.

Field experience has shown condensate drain traps with an open vertical Tee between the air handler and the condensate
drain trap can improve condensate drainage in some applications, but may cause excessive air discharge out of the open
Tee. The manufacturer does not prohibit this type of drain but we also do not recommend it due to the resulting air
leakage. Regardless of the condensate drain design used, it is the installer’s responsibility to ensure the condensate drain
system is of sufficient design to ensure proper condensate removal from the coil drain pan.

Use of a condensate removal pump is permitted when necessary. This condensate pump should have provisions for
shutting off the control voltage should a blocked drain occur. A trap must be installed between the unit and the conden­sate pump.

IMPORTANT NOTE: The evaporator coil is fabricated with oils that may dissolve styrofoam and certain types of plastics.
Therefore, a removal pump or float switch must not contain any of these materials.
Tip: Priming the “P” trap may avoid improper draining at the initial installation and at the beginning of the cooling
season.

9 Ductwork

This air handler is designed for a complete supply and re­turn ductwork system.

To ensure correct system performance, the ductwork is to
be sized to accommodate 350-450 CFM per ton of cooling
with the static pressure not to exceed 0.5" in w.c. Refer to
ACCA Manual D, Manual S and Manual RS for information on duct sizing and application. Flame retardant ductwork is to
be used and sealed to the unit in a manner that will prevent leakage.

NOTE: A downflow application with electric heat must have an L-shaped sheet metal supply duct without any outlets or
registers located directly below the heater.

9.1 Return Ductwork

Do not operate this product without all the ductwork
attached.

DO NOT LOCATE THE RETURN DUCTWORK IN AN AREA THAT CAN INTRODUCE TOXIC, OR OBJECTIONABLE FUMES/
ODORS INTO THE DUCTWORK. The return ductwork is to be connected to the air handler bottom (upflow configu­ration).

10 Return Air Filters

Each installation must include a return air filter. This filtering may be performed at the air handler using the factory
filter rails or externally such as a return air filter grille. When using the factory filter rails, a nominal 16x20x1”, 20x20x1”
or 24x20x1” (actual dimension must be less than 23-½”x20”) filter can be installed on a B, C and D cabinet respectively
(the cabinet size is the seventh letter of the model number).

11 Electric Heat

Refer to the installation manual provided with the electric heat kit for the correct installation procedure. All electric
heat must be field installed. If installing this option, the ONLY heat kits that are permitted to be used are the HKS series.
Refer to the air handler unit’s Serial and Rating plate or the HKS specification sheets to determine the heat kits compat­ible with a given air handler. No other accessory heat kit besides the HKS series may be installed in these air handlers.

The heating mode temperature rise is dependent upon the system airflow, the supply voltage, and the heat kit size (kW)
selected. Use data provided in Tables 2, 3 and 4 to determine the temperature rise (°F).

NOTE: For installations not indicated above the following formula is to be used:

TR = (kW x 3412) x (Voltage Correction) / (1.08XCFM)

Where: TR = Temperature Rise

kW = Heater Kit Actual kW
3412 = Btu per kW
VC* = .96 (230 Supply Volts)

= .92 (220 Supply Volts)
= .87 (208 Supply Volts)

1.08 = Constant
CFM = Measured Airflow

*VC (Voltage Correction)

9

NOTE: The Temperature Rise Tables can also be used to estimate the air handler airflow delivery. When using these
tables for this purpose set the room thermostat to maximum heat and allow the system to reach steady state conditions.
Insert two thermometers, one in the return air and one in the supply air. The temperature rise is the supply air temperature
minus the room air temperature. Using the temperature rise calculated, CFM can be estimated from the TR formula
above. See Technical Manual and/or Service Manual for more information.

Measure the power supply to the unit. The supply voltage must be measured and be in agreement with the unit
nameplate power requirements and within the range shown.

12.2 Wire Sizing

Wire size is important to the operation of your equip­ment. Use the following check list when selecting the
appropriate wire size for your unit.

• Wire used must carry the Minimum Circuit Ampac-

ity (MCA) listed on the unit’s Series and Rating Plate.

• Refer to the NEC (USA) or CSA (Canada) for wire siz­ing. The unit MCA for the air handler and the op­tional electric heat kit can be found on the unit Se­ries and Rating Plate.

• Wire must be sized to allow no more than a 2% volt-

age drop from the building breaker/fuse panel to
the unit.

• Wires with different insulation temperature rating
have varying ampacities - be sure to check the tem­perature rating used.

Refer to the latest edition of the National Electric
Code or in Canada the Canadian Electric Code when
determining the correct wire size.

12.3 Maximum Overcurrent Protection (MOP)

Every installation must include an NEC (USA) or CEC
(Canada) approved overcurrent protection device.
Also, check with local or state codes for any special
regional requirements.

Protection can be in the form of fusing or HACR style
circuit breakers. The Series and Rating Plate pro­vides the maximum overcurrent device permissible.

FIRE HAZARD!
To avoid the risk of property damage, personal injury
or fire, use only copper conductors.

HIGH VOLTAGE!

Disconnect ALL power before servicing.
Multiple power sources may be present.
Failure to do so may cause property damage,
personal injury or death.

12.4 Electrical Connections – Supply Voltage

IMPORTANT NOTE: USE COPPER CONDUCTORS ONLY.

Knockouts are provided on the air handler top panel and
sides of the cabinet to allow for the entry of the supply
voltage conductors, as shown in Figure 13. If the knockouts
on the cabinet sides are used for electrical conduit, an
adapter ring must be used in order to meet UL1995 safety
requirements. An NEC or CEC approved strain relief is to be
used at this entry point. Some codes/municipalities re­quire the supply wire to be enclosed in conduit. Consult
your local codes.

12.4.1 Air Handler Only (Non-Heat Kit Models)

The building supply connects to the stripped black and red
wires contained in the air handler electrical compartment
cavity. A ground screw is also contained in this area. At­tach the Supply wires to the air handler conductors as shown in the unit wiring diagram using appropriately sized
solderless connectors or other NEC or CEC approved means.

12.4.2 Air Handler - Non-Circuit Breaker Heat Kits

A terminal block is provided with the HKS kit to attach the power supply and air handler connections. Follow the
HKS Installation Manual and wiring diagram for complete wiring details.

12.4.3 Air Handler With Circuit Breaker Heat Kit

Top of

Cabinet

KNOCK-OUT FOR ELECTRICAL CONNECTIONS

Figure 13

Side of

Cabinet

The air handler has a plastic cover on the upper access panel that will require either one or both sections to be
removed to allow the heat kit circuit breaker(s) to be installed. The circuit breakers have lugs for power supply
connection. See the HKS Installation Instructions for further details.

12.5 Low Voltage Connections

Several combinations of low voltage schemes are possible, depending on the presence of a heat kit and whether the
heat kit is single-stage or multi-stage, whether the outdoor section is an air conditioner or heat pump, and whether
the outdoor section is single-stage or two-stage. The 24V-control voltage connects the air handler to the room
thermostat and condenser. Low voltage wiring must be copper conductors. A minimum of 18AWG must be used for
installations up to 100 feet. Low voltage wiring must be connected through the top of the cabinet or either side.
See the “Thermostat Wiring” section of this manual for typical low voltage wiring connections.

12.5.1 Thermostats

Second-stage heat can be accomplished by a multi-stage heating thermostat or the addition of an outdoor thermo­stat as shown in wiring schematics on pages 14 and 15. Follow the thermostat manufacturer’s instructions for
installation.

12.6 Speed Tap Adjustment

ARUF**14** air handlers have multi-speed PSC motors. The color of the wire coming from the motor to the “COM”
terminal on the control board defines at which speed the motor will operate. Black wire is high speed, blue wire is
medium speed and red wire is low speed. To change speeds, remove the wire attached to the “COM” terminal on
the control board, and swap it with the wire (on terminal “M1” or “M2”) with the color that will give the desired
speed.

ASPT**14** air handlers feature energy efficient blower motors. The motors run at a constant torque with very low
power consumption and are energized by 24 VAC. Adjust the CFM by changing the 24 VAC leads to the desired speed
tap on the terminal block. The ASPT blower motor speeds are programmed to deliver adequate airflow at rated
external static pressure and with 60 second off time delay. For details, refer to the specification sheet applicable
to your model.

NOTE: In some models, not all speed taps are allowable for certain electric heat applications. Refer to Table 5 for
minimum speed.

13 Achieving 1.4% Low Leakage Rate

Ensure all the gaskets remain intact on all surfaces as shipped with the unit. These surfaces are areas between the upper
tie plate and blower access panel, blower access and coil access panels, and between the coil access and filter access
panels. Ensure upon installation, that the plastic breaker cover is sitting flush on the blower access panel and all access
panels are flush with each other and the cabinet. With these requirements satisfied, the unit achieves less than 1.4%
airflow leakage when tested in accordance with ASHRAE Standard 193.

14 Start-Up Procedure

• Prior to start-up, ensure that all electrical wires are properly sized and all connections are properly tightened.

• All panels must be in place and secured. For Air Tight application, gasket must be positioned at prescribed loca­tions to achieve 1.4% leakage.

• Tubing must be leak free.

• Condensate line must be trapped and pitched to allow for drainage.

• Low voltage wiring is properly connected.

• Auxiliary drain is installed when necessary and pitched to allow for drainage.

• Unit is protected from vehicular or other physical damage.

• Return air is not obtained from, nor are there any return air duct joints that are unsealed in, areas where there may
be objectionable odors, flammable vapors or products of combustion such as carbon monoxide (CO), which may
cause serious personal injury or death.

15 Regular Maintenance

The only item required to be maintained on a regular basis
by the user is the circulating air filter(s). Filter should be
cleaned or replaced regularly, typically once per month. A
certified service technician must perform all other services.

IMPORTANT NOTE: If thumb screws are used to access the
filter, ensure the washer installed on the screw behind the
access panel remains in place after re-installation.

HIGH VOLTAGE!
Disconnect ALL power before servicing or
installing this unit. Multiple power sources may
be present. Failure to do so may cause property
damage, personal injury or death.

Air Handler Low Voltage Connections

The following composite wiring diagrams detail various configurations in which the air handlers can be used. Examples
include single-stage cooling and heat pump with single or two-stage electric heating. All these configurations can be
applied with convenient connections to outdoor thermostat applications.

The following sections are detailed:

• Single-Stage Cooling

• Heat Pump

Each diagram details the connections between room thermostat and the air handlers, and the connections between the
air handlers and the Condensing Unit (or Heat Pump) with optional connections to Outdoor Thermostats. For each
configuration, refer to the explanation of the proper jumper(s) to remove for the corresponding blower speed that will
result in the programmed fixed speed ECM motor.

IMPORTANT: WHEN MATCHING THE ASPT AIR HANDLERS TO A SINGLE SPEED COOLING OR HEAT PUMP
UNIT, REMEMBER TO CONNECT “Y” FROM THE THERMOSTAT TO THE “Y2” ON THE LOW VOLTAGE
TERMINAL BOARD.

An equivalent thermostat can be used in place of the manufacturer’s thermostat part number.
NOTE: Some models feature low voltage wires and do not include a terminal block. For those applications use the

corresponding colored wires.

AIR CONDITIONING AND HEAT PUMP HOMEOWNER’S ROUTINE MAINTENANCE RECOMMENDATIONS

We strongly recommend a bi-annual maintenance checkup be performed before the heating and cooling seasons begin by a qualified servicer.

REPLACE OR CLEAN FILTER

IMPORTANT NOTE: Never operate unit without a filter installed as dust and lint will build up on internal parts resulting in loss of efficiency,

equipment damage and possible fire.
An indoor air filter must be used with your comfort system. A properly maintained filter will keep the indoor coil of your comfort system clean.

A dirty coil could cause poor operation and/or severe equipment damage.
Your air filter or filters could be located in your furnace, in a blower unit, or in “filter grilles” in your ceiling or walls. The installer of your air

conditioner or heat pump can tell you where your filter(s) are, and how to clean or replace them.
Check your filter(s) at least once a month. When they are dirty, replace or clean as required. Disposable type filters should be replaced.

Reusable type filters may be cleaned.
You may want to ask your dealer about high efficiency filters. High efficiency filters are available in both electronic and non-electronic types.

These filters can do a better job of catching small airborne particles.

COMPRESSOR

The compressor motor is hermetically sealed and does not require addi­tional oiling.

MOTORS

Indoor and outdoor fan motors are permanently lubricated and do not
require additional oiling.

ALUMINUM INDOOR COIL CLEANING (QUALIFIED SERVICER ONLY)

This unit is equipped with an aluminum tube evaporator coil. The safest
way to clean the evaporator coil is to simply flush the coil with water.
This cleaning practice remains as the recommended cleaning method for both copper tube and aluminum tube residential cooling coils.

An alternate cleaning method is to use one of the products listed below to clean the coils. The cleaners listed below are the only agents
deemed safe and approved for use to clean round tube aluminum coils.

Trade Name: Part/Product Manufacturer
EVAP-Green 4191-08 Nu-Calgon
Extreme Simply Green
Aircraft Precision Cleaner 13406 Sunshine Makers, Inc.

NOTE: Ensure coils are rinsed well after use of any chemical cleaners.

CLEAN OUTSIDE COIL (QUALIFIED SERVICER ONLY)

Air must be able to flow through the outdoor unit of your comfort system.
Do not construct a fence near the unit or build a deck or patio over the
unit without first discussing your plans with your dealer or other quali­fied servicer. Restricted airflow could lead to poor operation and/or se­vere equipment damage.

Likewise, it is important to keep the outdoor coil clean. Dirt, leaves, or
debris could also restrict the airflow. If cleaning of the outdoor coil be­comes necessary, hire a qualified servicer. Inexperienced people could
easily puncture the tubing in the coil. Even a small hole in the tubing
could eventually cause a large loss of refrigerant. Loss of refrigerant can
cause poor operation and/or severe equipment damage.

Do not use a condensing unit cover to “protect” the outdoor unit during
the winter, unless you first discuss it with your dealer. Any cover used must include “breathable” fabric to avoid moisture buildup.

BEFORE CALLING YOUR SERVICER

•

Check the thermostat to confirm that it is properly set.
Wait 15 minutes. Some devices in the outdoor unit or in programmable thermostats will prevent compressor operation for awhile, and

•
then reset automatically. Also, some power companies will install devices which shut off air conditioners for several minutes on hot
days. If you wait several minutes, the unit may begin operation on its own.

Check the electrical panel for tripped circuit breakers or failed fuses. Reset the circuit breakers or replace fuses as necessary.

•
Check the disconnect switch near the indoor furnace or blower to confirm that it is closed.

•

•

Check for obstructions on the outdoor unit . Confirm that it has not been covered on the sides or the top. Remove any obstruction that
can be safely removed. If the unit is covered with dirt or debris, call a qualified servicer to clean it.

Check for blockage of the indoor air inlets and outlets. Confirm that they are open and have not been blocked by objects (rugs, curtains

•
or furniture).

Check the filter. If it is dirty, clean or replace it.

•
Listen for any unusual noise(s), other than normal operating noise, that might be coming from the outdoor unit. If you hear unusual

•
noise(s) coming from the unit, call a qualified servicer.
